ABSTRACT:
A sheet sub-stack separating and feeding apparatus comprises a device for holding down sheets independently laid one upon the other in a stack, a device for detecting the level of a sheet in a predetermined position as numbered consecutively from above, a sheet sub-stack raising member standing face to face with a side end face of the stack for horizontal and vertical movements, and a device for grasping a predetermined number of sheets as one sub-stack and adapted for horizontal and vertical movements. The sheet sub-stack raising member is moved to the level detected by the sheet level detecting device, inserted under the top sub-stack while it is held down, and then moved up to raise an end portion of the stack. The forward end portion of the sheet sub-stack raising member is then swung down to hold down the sheets under the sub-stack. The sheet sub-stack grasping device is then moved horizontally to grasp the end portion of the sub-stack and to separate the sub-stack from the stack.
